i had to rplace my lower intake manifold and i decided to remove my oil injectors and plug the holes that are left by them and remove the oil injector vacuum spider because most of the hoses were broken. my question is now i have these to hard vacuum lines and i cant remember what goes to them. one of them is located inbetween the two lower fuel injectors and the other is a hard line coming of the big vacuum rats nest and is located just to the left of the lower fuel injectors. does anyone know what these go to. are they vacuum lines going to the oil injectors? is so should i just cap them off. any help would be great.

 

is it a TII? NA?

 

sorry it's a t2

 

if they're on a spider (1 hose->4hoses) then u can take the whole thing off and cap it. that's from the oil injectors

 

the hard ones hmm.... I know what u are talking about probably just cap them off, just trace where they go, u can do it.

 

Check the routing diagram for the OMP in the factory service manual (FSM) under lubrication (I would have uploaded a pic here but I don't know if you have s4 or s5)



FSM, you can get at www.fc3s.org under how-to's->manual, free



BTW, OMP lines are not vacuum lines



or, you could just get rid of the OMP (if it's mechanical, if electrical and controlled by ECU, leave it) and go pre-mix.
